The 32bits xlC is now perfectly clean, congrats !

A couple of warnings that's all:
http://www.cdash.org/CDash/viewBuildError.php?type=1&buildid=439244


However, there are still two issues remaining with xlC -q64 (64bits
compilation) :
http://www.cdash.org/CDash/viewTest.php?onlyfailed&buildid=439310

I do not understand what I need to adjust to get the path right, for instance:

> file /usr/lib/qt3/lib/libqt-mt.so.3.3.7
/usr/lib/qt3/lib/libqt-mt.so.3.3.7: ELF 32-bit MSB shared object,
PowerPC or cisco 4500, version 1 (SYSV), stripped
> file /usr/lib/qt3/lib64/libqt-mt.so.3.3.7
/usr/lib/qt3/lib64/libqt-mt.so.3.3.7: ELF 64-bit MSB shared object,
cisco 7500, version 1 (SYSV), stripped

Thanks again !
